USCGC Chase (WHEC 718) was a High Endurance Cutter of the United States Coast Guard. She was laid down on October 26, 1966, at Avondale Shipyards in New Orleans, launched on May 20, 1967, and commissioned on March 11, 1968. Chase is the fourth of twelve Hamilton class, 378 feet (115 m) cutters, and the third cutter named in honor of Salmon Portland Chase. She was decommissioned on March 29, 2011, and transferred to the Nigerian Navy as an excess defense article under the Foreign Assistance Act as NNS Thunder (F90).

Chase is designed as a high endurance cutter. Her crossing range of at , and 80 feet (24 m) flight deck, capable of handling both Coast Guard and Navy helicopters, making Chase a platform for extended patrol missions. Her missions included enforcement of all U. S. maritime laws and treaties, fisheries conservation, marine pollution response, defense readiness, and search and rescue. Chase was one of the first naval vessels built with a combined diesel and gas turbine propulsion plant. Chases engineering plant includes two diesel engines, and two gas turbines, which can achieve a top speed of Two 13 feet (4 m) diameter controllable pitch propellers, combined with a retractable and rotatable bow propulsion unit, giving Chase high maneuverability. Chases capabilities are enhanced by advanced air search and surface search radars including the AN/SPS 73 digital surface radar system that incorporates a state of the art computerized collision avoidance system. Chase uses the Shipboard Command and Control System (SCCS) which uses a network of computers including large screen displays and a dedicated satellite network for communications. A closed circuit TV system will enable the commanding officer to monitor flight deck operations, machinery conditions, towing, damage control, and related activities from the bridge.

After being commissioned in 1968, Chase participated in Operation Market Time. From December 1969 to May 1970, under Commander, Task Force 115, Chase participated in more than twelve gunfire support missions in the Vietnam War. For her service, Chase was awarded the Navy Meritorious Unit Commendation and Vietnam Service Medal. Chase visited the ports of Subic Bay, Hong Kong, Bangkok, and Kaohsiung (Taiwan) on this patrol. In June 1970, Chase returned to her homeport in Boston, Massachusetts transiting the Panama Canal. Between September 1970 and December 1972, Chase assumed Ocean Station duties at various times on the Charlie, Delta and Echo stations. During this period Chase visited ports such as Guantanamo Bay Naval Base, Cuba and Kingston, Jamaica. In 1972 Chase transited the Arctic Circle, and visited England, Denmark, Norway, and Portugal. In 1973, Chase participated in Operation Seaconex, (COMCRUDESFLOT TWO), an exercise with a screen of seven destroyers and an amphibious assault ship, helicopter (LPH) carrying anti submarine warfare (ASW) helicopters and Harrier vertical take off and landing (VTOL) jets protecting a convoy from air, subsurface and surface threats. On this operation, Chase transited the Straits of Gibraltar and visited Portugal and Morocco. Between the years 1970 and 1974 Chase conducted three or four Search and Rescue cases daily while on various Ocean Station duties.

In 1977 Chase was among the cutters assigned to protect a part of the U. S. exclusive economic zone (EEZ) created as a result of passage of the Magnuson Stevens Fisheries Conservation and Management Act, protecting the area from Cape May, New Jersey to Cape Hatteras, North Carolina from foreign encroachment. In 1980, Chase was back in the U. S., on scene at the America's Cup in Newport, Rhode Island. In 1982, Chase participated in “Safe Pass 1982,” a member of the Fleet Composite Operational Group.

1981 Chase participated in the Mariel Boatlift, rescuing Cuban civilians in district 7; all crew received humanitarian medals. From October 1983 to July 1984, Chase served in Operation Urgent Fury, the U. S. invasion of Grenada. For her service Chase received the Armed Forces Expeditionary Medal. Until March 1988 Chase continued to display her versatility in performing all Coast Guard missions. Chase repatriated more than 338 migrants during its Haitian Migration Interdiction Operations (HMIO) between the January 1985 and March 1988 and also conducted many drug interdiction operations. An engine room fire on May 8, 1985, disabled the cutter as it was traveling 70 mile (113 km) southeast of Cape Cod. One crewman was killed. A Coast Guard helicopter removed the crewman's body to a Cape Cod funeral home, and the cutter Chilula was sent to tow the disabled cutter to Boston. In 1989, Chase was temporarily decommissioned and entered Bath Ironworks Shipyard in Portland, Maine, to undergo the Fleet Renovation and Modernization (FRAM) program. At Bath, Chase was virtually torn apart and reassembled with substantial improvements to many of her systems. Approximately seventy five percent of the shipboard electronics were changed or modified; a third of the existing engineering systems were overhauled or replaced; and major internal space reconfigurations improved the crew's living conditions.

On March 22, 1991, Chase returned after completing FRAM, and was recommissioned. After 23 years of service in Boston, Massachusetts, the Mayor of Boston proclaimed October 14, 1991, as "Chase Appreciation Day." Chase was to depart for her new homeport of San Pedro, California.
